Description

Technical Field

[0001] This utility model relates to the field of tire repair technology, specifically to an inner tube cover repair machine that is easy to self-adjust. Background Technology

[0002] During use, tires may suffer damage such as punctures and cracks due to various reasons (such as nails, glass shards, etc.). In order to extend the service life of tires and reduce replacement costs, tire repair is a common solution. Common tire repair involves heating and pressurizing to make the patch bond tightly to the tire, forming a strong repair layer. The repaired tire has better strength and durability, making it suitable for various usage scenarios. Tire repair can not only reduce resource waste, but also reduce vehicle maintenance costs.

[0003] For example, Chinese patent application number 2020203799267 discloses a tire hot patching machine, including an arched frame. The upper arm of the arched frame has a first threaded hole through which a clamping screw is threaded. The clamping screw is threaded into the first threaded hole. The upper end of the clamping screw has a first handle, and the lower end is connected to a heating element through a steering device, allowing the heating element to move freely in both horizontal and vertical dimensions. The support arm of the arched frame has a power switch and a timer device, which is used to control the energizing time of the heating element. This device has a simple structure and is easy to use, but the heating is uneven during the vulcanization process, resulting in poor adhesion between the patch and the tire.

[0004] Based on the above solutions, during tire repair, the shape of the patch is usually higher in the middle and lower at the edges. This shape difference leads to uneven stress on the patch during vulcanization, making it impossible to ensure a good stress distribution at the damaged tire area. Furthermore, uneven heating during vulcanization can cause honeycomb-like bubbles to appear at the edges of the patch, resulting in reduced adhesion between the patch and the inner tube, ultimately leading to cracking and affecting its use. Due to the temperature rise during vulcanization, the rubber in the patch moves, requiring manual and continuous adjustment of the patch's tightness to ensure the vulcanization effect.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0029] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0030] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0031] An embodiment of an inner tube sheath repair machine that is easy to adaptively adjust is provided by this utility model:

[0032] like Figures 1 to 5 As shown, the device includes a frame 1, a screw handle 2 on the frame 1, a first heating head 4 and a second heating head 5 below the screw handle 2, a mounting bracket 6 on the first heating head 4, an elastic component 7 on the mounting bracket 6, and a timer and a power switch mounted on the surface of the frame 1. The timer is used to control the power-on duration of the first heating head 4 and the second heating head 5, and the power switch controls the start and stop of the device.

[0033] like Figure 1 , Figure 2 As shown, a connector 3 is provided below the screw handle 2. The screw handle 2 is connected to the first heating head 4 through the connector 3. A threaded hole is provided at the position where the frame 1 is connected to the screw handle 2. A mounting groove is provided at the position where the first heating head 4 is connected to the mounting bracket 6. The first heating head 4 and the mounting bracket 6 are connected through the mounting groove, which facilitates installation and disassembly.

[0034] The second heating head 5 is mounted on the frame 1, and a fixing groove is provided at the position where the frame 1 connects with the second heating head 5. The second heating head 5 is located below the first heating head 4.

[0035] In use, manually turn the screw handle 2 to move the first heating head 4 up and down through the threaded connection. The first heating head 4 and the second heating head 5 are used to heat and repair the tire.

[0036] like Figure 3 As shown, a vent pipe 61 is provided on one side of the mounting bracket 6. The first heating head 4 has a positioning groove inside that matches the vent pipe 61. An inflation connector 62 is provided at the end of the vent pipe 61 away from the mounting bracket 6. An inflation hose 63 is provided at one end of the inflation connector 62. A miniature air pump is provided at the end of the inflation hose 63 away from the inflation connector 62.

[0037] like Figure 4 , Figure 5 As shown, the elastic component 7 includes an elastic sleeve 71, and an annular piece 72 is provided on the surface of the elastic sleeve 71. The annular piece 72 includes a first heat-conducting ring 721 and a second heat-conducting ring 722, and a limit component is provided on both the first heat-conducting ring 721 and the second heat-conducting ring 722.

[0038] The limiting component includes a fixed base 73, which is fixedly mounted on the mounting bracket 6. A spring 74 is installed inside the fixed base 73. A limiting rod 75 is provided at the end of the spring 74 away from the fixed base 73. A limiting groove is provided at the position where the fixed base 73 connects with the limiting rod 75. The limiting rod 75 is slidably mounted on the fixed base 73. With the spring 74, the limiting rod 75 slides in the limiting groove of the fixed base 73 under the action of the spring 74. Through the combination of the fixed base 73, the spring 74 and the limiting rod 75, the deformation range of the elastic sleeve 71 is limited, avoiding uneven force or damage due to excessive deformation.

[0039] When in use, the controller turns on the micro air pump, and the gas enters the interior of the mounting frame 6 through the inflation hose 63, inflation connector 62, and vent pipe 61. Since the mounting frame 6 and the elastic component 7 are assembled to form a closed space, the amount of gas in the closed space increases during the inflation process. Under the action of the gas, the elastic sleeve 71 undergoes elastic deformation, thereby conforming to the shape of the patch and adapting to patches of different thicknesses.

[0040] like Figure 5 As shown, the diameter of the first heat-conducting ring 721 is larger than the diameter of the second heat-conducting ring 722, and the first heat-conducting ring 721 and the second heat-conducting ring 722 are spaced apart inside the elastic sleeve 71.

[0041] Two limiting components are respectively provided on the first heat-conducting ring 721 and the second heat-conducting ring 722, and the two limiting components are symmetrically arranged. This symmetrical design can ensure the balance of the first heating head 4 and the patch under force, and avoid damage or uneven repair caused by uneven local force.

[0042] It is worth noting that the first heat-conducting ring 721 and the second heat-conducting ring 722 are used to conduct heat. Since the diameter of the first heat-conducting ring 721 is larger than that of the second heat-conducting ring 722, the two are set at intervals to meet the thickness difference between the middle and the edge of the patch of different specifications and to enhance the adaptability of the elastic sleeve 71 to the shape of the patch.

[0043] During tire repair, the shape of the patch is typically higher in the middle and lower at the edges. This shape difference leads to uneven stress distribution during vulcanization, making it difficult to ensure proper stress distribution at the damaged tire site. Furthermore, uneven heating during vulcanization can cause honeycomb-like air bubbles to form at the edges, reducing adhesion between the patch and the tire and ultimately leading to cracking and affecting usability. The temperature rise during vulcanization causes rubber creep within the patch, requiring continuous manual adjustment of the patch's tightness to ensure effective vulcanization. To address this issue, the following measures are taken:

[0044] First, the damaged area of ​​the tire is cleaned. After cleaning, the damaged area is identified and marked. Then, the damaged area on the inner surface of the tire is roughened using a grinding tool to increase the friction between the patch and the damaged area. The roughened debris is then cleaned away. A suitable patch is then selected and applied to the damaged area. The tire is then fixed onto the frame 1 according to the patch's position, aligning the center of the first heating head 4 with the center of the patch. The screw handle 2 is then manually rotated, moving it vertically downwards. This causes the connecting piece 3 and the first heating head 4 to move. The mounting bracket 6 and the elastic component 7 move together with the first heating head 4, bringing the elastic sleeve 71 on the elastic component 7 into contact with the patch surface. During this process, the spring 74 is compressed, and the limiting rod... 75 moves along the limiting groove on the fixed seat 73 towards the first heating head 4. When the detection value of the pressure sensor in the fixed seat 73 on the second heat-conducting ring 722 reaches the preset threshold range, the screw handle 2 is stopped, so that the first heating head 4 stops moving, thus completing the initial fixation of the tire. Then, the controller turns on the micro air pump, and the gas enters the interior of the mounting frame 6 through the inflation hose 63 and the inflation connector 62. Since the mounting frame 6 and the elastic component 7 are assembled to form a closed space, the amount of gas in the closed space increases during the inflation process. Under the action of the gas, the elastic sleeve 71 undergoes elastic deformation. The detection values ​​of the pressure sensors in the fixed seat 73 on the first heat-conducting ring 721 and the fixed seat 73 on the second heat-conducting ring 722 are respectively recorded as pressure value A and pressure value B. When the pressure values ​​A and B remain unchanged, it indicates that the elastic sleeve 71 is tightly fitted with the patch. At this time, the air pump is turned off. This operation effectively solves the problem of uneven force on the patch during the subsequent vulcanization process, which leads to a decrease in the adhesion between the patch and the tire.

[0045] Then turn on the power switch. The controller controls the heating time on the timer. At this time, the first heating head 4 and the second heating head 5 are powered on and start working. After the timer reaches the set time, the vulcanization ends. Turn off the power switch and then manually turn the screw handle 2 to move the screw handle 2 in the vertical direction, so that the elastic sleeve 71 is separated from the patch. The tire repair is completed. Finally, remove the tire.

[0046] During the above process, the rubber in the patch moves due to the temperature rise during vulcanization. At this time, the detection values ​​of the pressure sensor in the fixing seat 73 of the first heat-conducting ring 721 and the pressure sensor in the fixing seat 73 of the second heat-conducting ring 722 change. In order to ensure the vulcanization effect, the controller controls the air pump to continue to inflate the air hose 63, increasing the amount of gas in the closed space formed by the first heating head 4, the mounting bracket 6 and the elastic component 7. Under the action of the gas, the elastic sleeve 71 undergoes elastic deformation, the spring 74 is stretched, and the limiting rod 75 moves away from the first heating head 4 along the limiting groove on the fixing seat 73, pushing the first heat-conducting ring 721 and the second heat-conducting ring 722, thereby increasing the pressure of the elastic sleeve 71 on the patch, which can adjust the tightness of the patch in time.

[0047] It is worth noting that the inflation connector 62 is equipped with a control valve, which opens when air is introduced through the inflation hose 63 and closes when air is introduced through the hose.

[0048] During the vulcanization process, the mounting bracket 6 and the elastic component 7 work together to allow the elastic sleeve 71 to automatically adjust according to the shape of the patch. That is, when the middle of the patch is higher than the edges, the elastic sleeve 71 will automatically sink and fill the low-lying areas, ensuring that the entire surface of the patch is in close contact with the tire. In addition, by setting the first heat-conducting ring 721 and the second heat-conducting ring 722, heat can be evenly conducted. During the heat transfer process, the gas temperature in the enclosed space rises, thereby providing auxiliary heating and making the patch heat evenly. This results in stronger patch adhesion, a more stable repair structure after vulcanization, and higher durability. This effectively solves the problem of uneven heating during vulcanization caused by the shape difference of the patch, where the middle part of the patch is overheated while the edges are underheated. This also avoids the formation of honeycomb-like bubbles at the edges of the patch, which would reduce the adhesion between the patch and the tire and eventually lead to cracking.

[0049] It is worth noting that a pressure sensor is installed inside the mounting base 73. The pressure sensor can detect the pressure on the annular piece 72 in real time. Specifically, the pressure sensor in the mounting base 73 on the first heat-conducting ring 721 can detect the pressure on the first heat-conducting ring 721, and the pressure sensor in the mounting base 73 on the second heat-conducting ring 722 can detect the pressure on the second heat-conducting ring 722. This allows the pressure on the middle and edge positions of the patch to be determined, thus enabling timely adjustment of the pressure on the patch during the repair process.
